Magura’s new MCi brake & handlebar setup is the sleekest hydraulic disc brake mountain bike cockpit you will find, hiding the brake master cylinder inside of the handlebar itself. With all of the hydraulics & brake hoses tucked into the bar’s end via a self-contained unit, all that is left to see on the outside is a low-profile lever & clamp for a super sleek cockpit setup.

Magura cockpit integration (MCi) brakes INSIDE your bar

Magura calls their Cockpit Integration (MCi) the “world’s first hydraulic brake… fully integrated into the handlebar”. Putting the brake master cylinder & brake lines inside results in a clean & tidy look, promising improved protection and also better aerodynamics.

However, they also point out that the design is about more than just looks – because the design allows them to use a ‘pull cylinder’ instead of a ‘push cylinder’, we’re told that the levers should offer improved functionality while protecting the master cylinder in the event of a crash.

Tech details

The entire system is actually relatively simple, and shouldn’t be that difficult to set up or maintain. The hydraulics themselves are in a contained unit that slides into the end of a standard handlebar, just like a bar plug. Then, through a small hole in a compatible mountain bike bar, the external brake lever pulls an internal sliding rod to activate the internal master cylinder.

The trick there of course is that it will only work with a compatible bar with the correct hole in it. The trail bike they show here is built with a carbon bar from Bike-Ahead Composites. And that means the position of the brake lever body itself will be somewhat limited by the location of the pre-cut hole/port.

There is a good amount of adjustability from what we’re told – but it may not be ideal for anyone who likes their brakes far away from the grip, or tilted up or down at a more extreme angle.

Of course you will also need an internal routing friendly bar-to-stem, and opening in the frame to make it all work internally. But if you can tick all of those boxes, it will lead to a tidy setup. The bike that we saw had an opening in the downtube where the rear brake hose and Di2 wires entered from the bottom of the steerer tube. The front brake hose then just traveled down to the front brake.

Magura says the system uses a new Easy Link coupler on the end of the hydraulic brake lines where they go through the headset, which should just snap into place. It says that the system can be plugged & unplugged for setup & servicing without losing oil.

Directly accessible from the end of the bar, it should be easy to bleed the brakes – although it appears that you will need to alternately lay the bike on its side to do so.

The new MCi brake lever uses the same dimensions for the expansion reservoir and piston diameter as the MT series brakes. That means it will give the same braking performance as their top MT8 brakes, and also makes a straightforward upgrade option for their most common 2-piston or 4-piston brake caliper family, now with next-level cockpit integration.

MCi integrated brake availability?

The new MCi brake levers will be first available only as original equipment on complete bikes spec’d together with Magura. No aftermarket version is expected in the near future. No word yet on what will be the first bikes to feature MCi with 2019 consumer availability. But Magura teased that we will get to test ride the first production bike with the new kit when we head to Tirol in just over one week, so we’ll let you know then.

Why begin with standard parts here.?..This is a pretty fundamental shift so let an industrial designer re-think the fork-stem-bar interface and this could probably be done in an elegant yet stll accessible way.

I’ve owned a pair of mt7s for years and never had to bleed them. Total dream as far as breaks.

My only real question, what was the problem they are trying to solve with this system?

Bar removal for easier boxing? In our Pro Bike Mechanics world of internal everything…..why not? Quick dis-connects are interesting. Someone should make a system for external routing with quick dis-connects at the levers and the caliper allowing for easy hose changing for adapting brakes to different sized frames without the need to bleed. This tech could be game changing.

I do hope road bikes adapt the whole quick disconnect as well since everything is becoming wayyyyyy integrated making bike travel an annoyance.

Because cables are a problem? I kind of feel like we are reaching a point if over doing it here….. Seems like some small tweaks to the brake cylinder would allow the lines to run closer to the bars and frame without all the internal stuff. Also future choice becomes limited.

Speechless! I thought I hated internal routing in general but this cranks it up to 11.

This is really beautiful, but I think I’d worry about being able to adjust the lever angle to my preferred position, and about having the brake fixed in position such that it couldn’t rotate in a crash (I was taught to keep brakes firm, but not so firm that they couldn’t rotate a bit in case of a hard crash).

Your comment on bar clamp should rotate in a crash hit the nail on the head. This system is potentially less crash resistant for this reason. Good call.

Isn’t external routing much easier to work on?

Tim

It looks like you can’t adjust the brake levers’ positions much. It also looks like the master cylinders can fit only in certain bars. It looks to me more like an aesthetic move than a functional one, and one that reduces your choice of handlebars down to just one.

what problem does this solve? Because it definitely creates problems such as adjustability, serviceability. This looks like the definition of long haul, short slide.

“Of course you will also nee an internal routing friendly bar-to-stem, steerer-to-fork leg, and stem-to-headset-to-frame interface to make it all work internally. ”

Are there any fork companies making steerer tubes with open slots in them (entry + exit)? That seems like as big a challenge as fitting the MC’s in the bar.

Drill a big hole and die grind it out. Boom, Steerer tube is now compatible.

With the next generation of hydro road bikes all going internal routing for the cables, I do hope they’ll do something like this which allows the hydraulic cable to be disconnected for situations where you need to remove the handlebar and stem, (likely for those bike bags that requires handlebar and or stem removal).

I dig it. Not quite fully sorted I think, but still a solid attempt.
Connectamajigs are a thing already. SRAM road hydro have them built in.

I really like this. I think it is great how it hides the brake lines and just looks so damn clean. Functionally, it is not doing anything special, but just the aesthetics of it are awesome. Hat is off to Magura.
Combine with a wireless electric shift system and you can have a cable free cockpit!

What are you suppose to grab onto when you’re doing the “phantom” aerobar position?

Gillis

On a road bike where aerodynamics is a legit consideration, it makes sense. This, not so much. Like others, it’s an answer in search of a question. Unless aesthetics are a big deal for you.

The only thing i like about this is the quick disconnects. They work great in hydraulic systems though I feel like they’d introduce air in closed systems like this. Other than that I’d hate to service these things. Not to mention adjustability, compatibility, etc.

What a monumentally stupid idea! Crash protection for the master cylinder?!! I’ve never damaged a MC in 20years of riding disc brakes. I have bent the lever because it too tight on the bar and didn’t shift in an accident. With this thing the bar or MC will break.
It looks like an absolute nightmare to work on. Hey Magura, how about focusing on making brakes great again rather than trying to catch our attention with dumb ideas. How about that wireless dropper you were working on?

1. crash bike, drop bike, hit bar on ground, reck master cylinder!
2. restricted to their bar and brake location.
3. pain in the ass to fix, work on.
4. whats wrong with what we have now?

Why? You still have a ton of cable housing and hose coming out of the steerer tube and down the for etc. All you’ve added is a slight modicum of cleanliness to the bars but that could be resolved by some slick industrial design on the master cylinder. And for that you have a trade off of proprietary bars, grips, limited serviceability, limited adjustment and for what? Aerodynamics? On a MTB? I don’t get what problem this product is trying to solve.

Why would manufactures be creative? I don’t understand why anyone tries anything new ? There are plenty of old ways of doing things. I say we should all stop using our brains to think of possible new ways to do things. It will just create new problems. I don’t want new problems. I like my old problems. I only
want to see innovations that come with no new problems. I only accept perfection, otherwise I’ll call you stupid for even trying.

I think, trickstuff Picola brakes approach is much better, lighter, simpler, and slicker. And it’s been in the market for years now. This is gonna be discountinued in 2 seasons max.

I think the idea is great and it is a platform to build upon! Yes, it has a ways to go to be refined and no it is not for everyone or every bike. I can’t see this being practical on trail/enduro bikes but in the next five years someone will be racing on an aero XC bike with this concept but fully integrated in the frame like the road bikes. Think back only 5 years ago at the things “bike experts” thought was stupid but is a standard now. Haters gonna hate but the bike industry wouldn’t be where it is now without “stupid” ideas like this.
Keep moving forward, I’m excited for any innovation in the bike industry, stupid or not.

I leave my brakes only just nipped up enough so in a crash they will rotate on the bar and not snap, that would be fatal to the lever and MC and a carbon bar with these

Robert Buss

The advantage of this setup is a bigger master cylinder, than one is inclined to hang off a brake lever.
